Abstract (en)
A lighting device may include a plurality of LED light sources, a plurality of lens parts respectively disposed on front surfaces of the plurality of LED light sources to collect and irradiate light emitted from each of the plurality of LED light sources, and a controller for controlling operations of the plurality of LED light sources. The plurality of LED light sources may include visible-light LEDs and at least one ultraviolet LED. Each of the plurality of lens parts may include a condensing lens disposed on the front surface of each of the plurality of LED light sources to decrease a divergence angle of light emitted from each of the plurality of LED light sources and a fly eye lens part disposed on a front surface of the condensing lens to stack the light on a light receiving surface so that a light quantity at the light receiving surface has a uniform distribution.
